Abstract
The invention discloses a safety valve with a pressure alarm. The safety valve with the pressure alarm comprises a seal cover, a valve rod, a spring, a valve body, a valve clack, a guide sleeve, the pressure alarm and an air inlet connector. The upper end of the valve rod is connected with a protective cover. The lower end of the valve rod penetrates through the spring and then is sequentially connected with the guide sleeve and the valve clack. The pressure alarm is perpendicularly installed on the air inlet connector. An air inlet of the pressure alarm is communicated with the air inlet connector. By arranging the pressure alarm in the safety valve, property loss and casualties caused by accidents can be prevented; meanwhile, the service life of a device and the service life of the safety calve are both prolonged, and the safe reliability of the safety valve is improved greatly. The safety valve with the pressure alarm further has the advantages of being low in cost, convenient to use and the like.
Description
Technical field
The present invention relates to a kind of safety valve, particularly relate to a kind of safety valve with pressure alarm.
Background technique
Spring micro-open type safety valve is to utilize the power of Compress Spring to carry out the power of balanced action on flap.The decrement of spiral coil spring can regulate by the adjusting nut rotating above it, utilizes this structure just can proofread and correct as required unlatching (adjusting) pressure of safety valve.The light compactness of spring micro-open type safety valve structure, sensitivity is also higher, and mounting point is unrestricted, and also since little to the receptance of vibration, so can be used on portable pressurized container.The shortcoming of this safety valve is that added load can change along with the unlatching of valve, and, along with the rising of flap, the decrement of spring increases, and the power acting on flap also and then increases.This rapid unlatching to safety valve is disadvantageous.In addition, the spring on valve can be owing to being subject to for a long time the impact of high temperature that elastic force is reduced.For on the higher container of temperature time, usually to consider the heat insulation or heat dissipation problem of spring, thereby make structure become complexity.Existing Direct spring loaded safety valve was used after a period of time, and the elastic force of spring reduces, even when pressure exceedes authorized pressure, and also not take-off of safety valve.
Summary of the invention
The object of the invention is to provide in order to address the above problem a kind of safety valve with pressure alarm with warning function, long service life and low cost of manufacture.
The present invention is achieved by the following technical solutions:
A kind of safety valve with pressure alarm; comprise sealing cover, valve rod, spring, valve body, flap, guide sleeve, intake interface and pressure alarm; the upper end of described valve rod is connected with described safety cover; the lower end of described valve rod is connected with guide sleeve and flap successively through after spring; described pressure alarm at right angle setting is on described intake interface, and the suction port of described pressure alarm is communicated with described intake interface.
When the pressure in equipment exceedes the pressure of regulation, steam in safety valve intake interface enters pressure alarm can make pressure alarm give the alarm, remind operator's hand off power supply, the pressure drop in equipment is arrived in the scope allowing, can continue to use.By pressure alarm is set in safety valve, can prevent property loss and casualties that contingency brings.
Further, described pressure alarm comprises that pressure alarm comprises support, alarm spring, diaphragm, warning circuit plate, rocker, pressure chamber, contact and pedestal, described alarm spring is fixed on described diaphragm top, one end of described contact is fixed on described rocker, the other end contacts with warning circuit plate, described warning circuit plate is installed on described support, described rocker and support are rotationally connected, described support is arranged at described pedestal top, in described pedestal, be provided with vent, the top of described vent is communicated with described pressure chamber.
Steam enters after pressure alarm, when diaphragm experiences in pressure chamber that pressure source changes, just promotes deformation of elastic components.During pressure superpressure, diaphragm promotes one end of rocker and slides on the upper surface of diaphragm, and when contact contacts with described warning circuit plate, warning circuit plate gives the alarm.
Further, described pressure chamber is the airtight cavity being become with pedestal riveting by diaphragm.
As preferably, described safety valve also comprises spanner, and described spanner is fixed on the outer wall of described valve body.
The invention has the beneficial effects as follows:
By pressure alarm is set in safety valve, can prevent property loss and casualties that contingency brings, also extended the working life of equipment and safety valve simultaneously, greatly improved the safety reliability of safety valve.The present invention also has the advantages such as cost is low, easy to use.
